scandalous incompetence or pure ignorance? – Dept of Work and Pensions

This post should be read with caution – see comment trail. I’ll leave it in place anyway as a historical reference ūüôā The DWP is sitting on a block of¬†16,777,216 IP addresses. That’s a /8 block of IPv4 addresses for those that understand these things,¬†covering 51.0.0.0 to 51.255.255.255. The point is that none of these […]

APNIC starts to ration IPv4 addresses #ipv6

The Asia Pacific Regional Registry APNIC has, as of today, begun to ration IPv4 addresses. Down to its last /8 block (around 16 million addresses) APNIC will now only be issuing ¬†existing users with /22 blocks of 1,024 addresses and is urging its customers to accelerate their adoption of IPv6.

testing your endpoint for ipv6 readiness

IPv6 is very much in vogue at the moment. ¬†test-ipv6.com is a useful site you can visit that tells you how prepared you/your connection/your ISP are for IPv6. I’ve run some tests on two connections for you to compare the results. One is IPv4 only and the other dual stack IPv4/IPv6. The difference is self […]

Last 2 IPv4 blocks allocated – STOP PRESS

The last two available /8 blocks of IPv4 addresses have been allocated by IANA to APNIC.¬† This takes the remaining total down to 5 which means the IPv4 address pool is effectively exhausted. The last 5 are spoken for. There are no more. That’s it :). I’m holding off crying “history, history” until the remaining […]

OMG the internet is about to run out of addresses what should I do?

Media interest in IPv6 last week prompted a few questions, notably on twitter, regarding whether people should worry about the IPv4 address pool exhaustion. It would be easy to make noise and attract attention by saying ‚ÄúOMG yes ‚Äď you should worry‚ÄĚ. After all it is a fairly momentous event ‚Äď> ‚ÄúThe End of The […]

The end of #IPv4 and the coming of #IPv6 – exclusive interview with The Young Journalist Academy

Over the past few days I have had a flurry of media interviews on the subject of the exhaustion of the IANA IPv4 address pool and the advent of IPv6. This is increasingly going to be a talking point during 2011. The biggest problem in linking to these interviews is that they are usually on […]

Stop press ipv4 pool down to 2% as 4x /8s allocated in November

The title says it all. I’m travelling at the moment with only an iPad to create posts with but I note on the wire that the IANA address pool is down to 2%. I will need to revise my exhaustion date but february is either looking good or too late. My main concern is that […]

IPv6 to IPv4 tracert showing NAT

  Adrian Kennard of AAISP gave a talk on their implementation of¬†IPv6 ¬†at yesterday’s UK Network Operators Forum (UKNOF).¬† Whilst it may not be of huge interest to most readers it is worth taking a look at how the old IPv4 and new IPv6 networked worlds will talk to each other. The picture below represents […]

IPv4 exhaustion date is Sept 5th 2011

I note that the number of available¬†IPv4 addresses has dropped below the 10% mark. This is displayed on the counter on the right hand column of this blog but it took a link to the Number Resource Org on Facebook to alert me to the fact. This year should see an intensification of efforts to […]

IPv4 – the end is nigh?!

The IPv4 situation is already known to geeks everywhere. This is the protocol version that has been¬†used by IP networks everywhere since the year dot (approximately). The number of IPv4 addresses the world can use is fixed because these addresses use 4 Bytes of data.¬†The growth in IP networks everywhere¬†is consuming IPv4 addresses at¬†lightning speed. […]
